Abstract:
Microalgae are one of the most promising feedstocks for biodiesel production due to their high lipid content and easy farming. However, the extraction of lipids from microalgae is energy intensive and costly and involves the use of toxic organic solvents. Compared with organic solvent extraction, supercritical CO2(SCCO2) has demonstrated advantages through lower toxicity and no solvent-liquid separation. Due to the nonpolar nature of SCCO2, polar organic solvents such as methanol may need to be added as a modifier in order to increase the extraction ability of SCCO2. In this paper, pilot scale

Abstract:
medicine, industry, and biotechnology. Fungi produce a wide range of bioactive compounds, such as alkaloids, antibiotics, antifungals, immunomodulators, anticancer agents, enzymes, and vitamins. However, these compounds are often locked inside the fungal cell wall, which is composed of chitin, a tough substance that is dif�icult to digest by humans1. Therefore, it is essential to have a good extraction technique that can break down the chitin and release the valuable compounds from the fungi, this is especially essential in the laboratory for accurate lab assays and potency determination durin

Abstract:
Part I: The purpose of the investigation was to develop the extraction process that was simple, practical and giving high yield. The maceration of dried powder of Garcinia mangostana fruit husk with ethyl acetate gave yellow crystalline powder of mangostin. The yield was calculated as 7.47%. The identification of the Garcinia mangostanahusk extract was carried out by thin-layer chromatography (TLC) and differential scanning calorimetry. The TLC of mangostin was done by using the alumina sheet and ethyl acetate: hexane (3:1) as mobile phase. The Rf value as compared with standard mangostin was
